Abstract

The invention relates to a wireless control full color LED display screen comprising a controller, a drive circuit and an LED unit board. The wireless control full color LED display screen is characterized in that the input end of the drive circuit is electrically connected with the controller. The output end of the drive circuit is electrically connected with the LED unit board. A bottom board of the LED unit board is evenly provided with LED devices. The bottom board of the LED unit board adopts a multilayered PCB circuit board. The bottom board of the LED unit board is respectively provided with a heat radiating layer. The controller comprises a communication module, a control module and a FLASH storage module. The control module, the communication module and the FLASH storage module are electrically connected in turn. The wireless control full color LED display screen is simple in the whole circuit structure. An adjustable voltage reference source is adopted to stabilize voltage so that production cost is reduced and the service life of the LED drive circuit is increased. The wireless control full color LED display screen can be operated in a wireless way so that a technical staff can perform corresponding operation without going to the onsite scene.

Description

A kind of controlled in wireless full-color LED display screen

Technical field

The present invention relates to a kind of LED display, particularly a kind of controlled in wireless full-color LED display screen.

Background technology

LED display is the large scale display system that integrates computer technology, photoelectron technology, microelectric technique, the information processing technology.LED display is by certain control mode, the display screen forming for the device array of the various information such as display text, figure, image, animation, market, video, video signal.In recent years, because semi-conductive making and processing technology are progressively ripe and perfect, light emitting diode (Light Emitting Diode, LED) is occupied an leading position increasingly in solid demonstration.Why in widespread attention it is and developed rapidly, be that the brightness that has with itself is high, operating voltage is low, power consumption is little, microminiaturizedly easily mate with integrated circuit, drive simply, the life-span is long, shock-resistant, steady performance is inseparable, and current just towards high brightness more, more high weather resistance, higher uniformity of luminance, higher reliability and panchromaticization future development.Therefore, the LED display being applied under outdoor scene is also more and more, so, if need to upgrade the displaying contents of LED display or the preset program of change LED display, need technician to operate to scene, make troubles to user's operation and maintenance.

Summary of the invention

In order to address the above problem, the invention provides a kind of full-color LED display screen with wireless communication function, make operating personnel needn't arrive scene and just can operate display screen.

Described communication module is GPRS module or gsm module or WIFI module; Described heat dissipating layer is aluminium base or copper base or iron substrate or aluminium alloy base plate.

Beneficial effect of the present invention is as follows:

1. controller of the present invention comprises wireless communication module, for display screen has increased wireless communication function, makes technician needn't go to scene can carry out corresponding operating;

2. described LED cell board of the present invention is respectively equipped with heat dissipating layer, has solved the problem that too high picture element density produces a large amount of heats and then causes the life-span reduction of LED;

3. LED cell board of the present invention adopts multilayer PCB circuit board, has effectively reduced electromagnetic interference (EMI), has increased the area of dissipation of LED simultaneously.

4. the whole circuit structure of LED drive circuit of the present invention is simple, adopt adjustable voltage reference source to carry out voltage stabilizing, be beneficial to the reduction of production cost, in this circuit without using capacitor, can solve and because capacitor life-span is short, cause whole LED drive circuit not long problem in serviceable life, realize the LED drive circuit growth in serviceable life.

Embodiment

The embodiment setting forth below represents and allows those skilled in the art to put into practice necessary information of the present invention, and illustrates and put into practice best mode of the present invention.Once read with reference to the accompanying drawings following description, those skilled in the art just will understand design of the present invention and will recognize the application of these designs of not illustrating especially herein.Should be appreciated that these designs and application fall into the scope of disclosure and the accompanying claims book.

As shown in Figure 1, a kind of controlled in wireless full-color LED display screen of the present invention, bycontroller 1,driving circuit 2, a plurality ofLED cell boards 3 of being spliced to form display screen integral body, formed, the input end of describeddriving circuit 2 is electrically connected atcontroller 1, the output terminal ofdriving circuit 2 is electrically connected atLED cell board 3, on the base plate of describedLED cell board 3, be evenly provided with LED device, the base plate of describedLED cell board 3 adopts multilayer PCB circuit board, the base plate of describedLED cell board 3 is respectively equipped with heat dissipating layer, and described heat dissipating layer is aluminium base or copper base or iron substrate or aluminium alloy base plate.Describedcontroller 1 comprisescommunication module 11,control module 12,FLASH memory module 13, and describedcontrol module 12,communication module 11 andFLASH memory module 13 successively order are electrically connected.Describedcommunication module 11 is GPRS module or gsm module or WIFI module, and described wireless communication module is GPRS module or gsm module or WIFI module; Described heat dissipating layer is aluminium base or copper base or iron substrate or aluminium alloy base plate.

Wherein,communication module 11 is responsible for the information of receiving remote main frame and is transmitted tocontrol module 12 andFLASH memory module 13, the information that 13 storages of FLASH memory module receive fromcommunication module 11,control module 12 is extracted corresponding command information according to preset program fromFLASH memory module 13 canned datas, and then this display screen is operated accordingly.

In concrete operations, use LED full-colour display screen of the present invention to carry out operated from a distance:

Whencommunication module 11 is GPRS module, on distance host, pass through GPRS transmission mode to the GPRS module transmission control command information of displayingscreen controller 1, for example control display screen change and show character, by original " welcome ", change " welcome again " into, send order " welcome again for change character-", after receiving, GPRS module is transmitted tocontrol module 12 andFLASH memory module 13,FLASH memory module 13 these control command information of storage,control module 12 is extracted order " change character " from this control command information according to preset program, and then display screen is operated, change the demonstration character of display screen into " welcome again ",
